Reptiles exhibit a variety of modes sex determination, including both temperature-dependent and genetic mechanisms. Among those species with chromosomes varying heterogamety (XX/XY ZZ/ZW) have been observed different degrees differentiation. Karyotype studies demonstrated that Gila monsters (Heloderma suspectum) ZZ/ZW determination this system is likely homologous to the in Komodo dragon (Varanus komodoensis), but little else known about their chromosomes. Here, we report assembly analysis...

Abstract Large-scale changes in the structure and cellular makeup of distal lung are a hallmark pulmonary fibrosis (PF), but spatial contexts that contribute to disease pathogenesis have remained uncertain. Using image-based transcriptomics, we analyzed gene expression 1.6 million cells from 35 unique lungs. Through complementary cell-based innovative cell-agnostic analyses, characterized localization PF-emergent cell types, established molecular basis classical PF histopathologic features...

Image-based spatial transcriptomics deliver gene expression measurements of RNA transcripts in tissue slices with single-molecule resolution and context preserved. Modern Graph Neural Network (GNN) models are promising methods for capturing the complex molecular cellular phenotypes tissues at single-transcript single-cell levels. A key application GNNs is detection domains or niches, that is, groups molecules and/or cells collaboratively work together to produce phenotypes. Due vast number...

Abstract Environmental enrichment (EE) is a robust intervention for reducing cocaine-seeking behaviors in animals when given during forced abstinence. However, the mechanisms that underlie these effects are not well-established. We investigated adult male rat transcriptome using RNA-sequencing (RNA-seq) following differential housing abstinence from cocaine self-administration either 1 or 21 days. Enriched, 21-day rats displayed significant reduction behavior compared to housed isolation....

Abstract Individual behavioral variation is ubiquitous across taxa and important to understand if we wish fully use data the ecology evolution of organisms. Only recently have studies individual in dispersal behavior become a focus research. A better understanding likely improve our population dynamics. In particular, dynamics critically small populations (endangered species) large (pest may be driven by unique variants. Here documented ballooning Western black widow spiderlings Latrodectus...

The dopamine D3 receptor is a prime target for developing treatments cocaine use disorders (CUDs). In this study, we conducted pre-clinical investigation of the therapeutic potential long-acting, partial agonist, MC-25-41. Male rats were pre-treated with MC-25-41 (vehicle, 1.0, 3.0, 5.6, or 10 mg/kg, intraperitoneal (IP)) five minutes prior to tests sucrose intake on either progressive ratio schedule reinforcement variable interval 60 s multiple consisting 4, 15-min components available in...

Abstract RNA-sequencing (RNA-seq) technology has led to a surge of neuroscience research using animal models probe the complex molecular mechanisms underlying brain function and behavior, including substance use disorders (SUDs). However, findings from rodent studies often fail be translated into clinical treatments. Here, we developed novel pipeline for narrowing candidate genes preclinical by translational potential demonstrated utility this model in three RNA-seq self-administration. This...
